24402-71-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 24402-71-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,4,0 and 2 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 24402-71:
(7*2)+(6*4)+(5*4)+(4*0)+(3*2)+(2*7)+(1*1)=79
79 % 10 = 9
So 24402-71-9 is a valid CAS Registry Number.
